Bottom Line:
The negative association between education and initiation was only seen for incomes below the median value.In spite of the presumably equal access to HPV vaccine in Norway, we found socioeconomic disparities in vaccine uptake.More studies are needed to explain the underlying factors responsible for the observed socioeconomic differences.

Mentions:
A total of 96 692 girls born between 1997 and 1999 were registered in the Norwegian Central Population Registry (figure 1). Dates of immigration, emigration and death were used to determine residency in Norway. Girls who were not residents of Norway during the entire programme year in which their birth cohort was offered HPV vaccination were excluded. A total of 91 405 girls were considered eligible for vaccination in the period.
